H A Drpc_pipe.ceda4f9b7 Tue Nov 06 12:05:36 CST 2007 J. Bruce Fields <bfields@citi.umich.edu> sunrpc: rpc_pipe_poll may miss available data in some cases

Pipe messages start out life on a queue on the inode, but when first
read they're moved to the filp's private pointer. So it's possible for
a poll here to return null even though there's a partially read message
available.
